DEVICE FOR THROWING MOTORS INTO GEAR.

SPECIFICATION forming part Of Letters Patent N0. 722,122, dated March 3,1903.

Application filed May 15, 1902. Serial No- 107A45. (No model.)

To all whom, it may concern.-

Be it known that I, LUDWIG MAURER, a subject of the Emperor of Germany,and a residentof Nuremberg, Bavaria, Germany, have invented certain newand useful Improvements in Devices for Throwing Motors Into and Out ofGear, of which the following is a specification.

This invention has for its object a device for throwing into gear thedriving mechanism of motor-cars,which mechanism is constituted by afriction-wheel gear. This improved arrangement, by means of which thedevice for throwing into gear is specially adapted for the purpose forwhich it is used, consists in the motor-shaft on one end of which thefriction-disk is fixed being mounted so as to be capable of beingdisplaced and being engaged at the other end by the lever for throwinginto gear, by means of which the motorshaft is displaced axially, andthereby the friction disk pressed against the frictionwheel revolublymounted in front of it.

The improved arrangement for throwing into gear is shown in one form ofconstruction in the accompanying drawing, in which said figurerepresents a plan view partly in section.

A crank-shaft Z) is revolubly and, within certain limits, adjustablymounted in the motor-casing ct. On one end of the crank-shaft afriction-disk cis fixed, which stands closely opposite an adjustablefriction wheel d, mounted on a revoluble shaft 7c. At the other asuitable slot in the lever e.

ment-lever e is pivotally mounted at one end on the car-frame h and atthe other end is connected by means of a suitable link-bar t' with ahandle arranged in proximity to the drivers seat in such a way that bypulling the handle the lever e is moved to the right from its positionshown in the drawing, and thereby the motor-shaft Z) is axiallydisplaced. Consequently'the friction-disk 0 comes in contact with thefriction-wheel d and when the lever e is firmly pulled is pressedagainst the said wheel, so that the rotation imparted to it by the motoris transmitted to the revoluble axle 7c of the friction-wheel, and thusto the rear-wheel axle of the motor-car. On the 5 5 rod e being releasedthe pressure on the friction-surfaces ceases, and the driving connectionbetween the motor and the rear-wheel axle is interrupted.

I declare that what I claim is In a device for throwing motor-shaftsinto and out of gear in motor-vehicles and the like, the combinationwith suitable supportingbearings, of a motor shaft journaled therein,having an elongated crank portion and having limited endwise movement, apitman connected to said crank to have sliding movement thereon, afriction-disk carried on the end of said shaft, a lever for moving saidshaft longitudinally, and a friction-wheel adjacent to saidfriction-disk and adapted to be engaged and disengaged by the movementof the shaft and disk, substantiallyas described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

LUDWIG MAURER.
